FIELD OF THE INVENTION

The present invention relates generally to systems and methods forimproving the 3D experience provided by playback and display of 3D mediacontent, and more particularly to systems and methods for providing 3Dcontent mediacentric solutions that greatly improve the quality andimpact and other desirable features of any 3D media content, whiledecreasing the required levels of computing power, and lowering thecomplexity of the necessary 3D media playback and 3D media displaysolutions, thus maximizing the 3D experience produced therefrom.

BACKGROUND OF THE INVENTION

Various tools for capturing, generating, processing, playing back anddisplaying three dimensional (3D) content media (especially motionvideo), have been available for quite some time. Display technologiesfor 3D content media in particular have evolved quite a bit from theearliest barely passable offerings which required the audience to wearflimsy “glasses” provided with a different (red or blue) lens for eacheye, to more advanced electronic “stereoscopic 3D” glasses equipped withremotely triggered liquid crystal display (LCD)-based lenses (acting asalternating individually controlled “shutters”), which provided itswearers with an engaging and quality “3D experience”, given properlyprepared 3D content media paired with the appropriate playback andcorresponding display technologies working on conjunction with the 3Dglasses.

However, this approach for providing a “3D experience” is quitecumbersome and very expensive to use and maintain, and has thus been ofvery limited commercial success, primarily being relegated to specialentertainment venues, such as certain IMAX theaters and high-endamusement parks. In addition to expensive, and relatively fragile,glasses being required for each member of the audience (which in somecases excludes those who cannot comfortably wear them), the lateststereoscopic 3D solutions require sophisticated and expensivecomputer-based components for storing and processing the 3D content, aswell as similarly complex and expensive electronic components fordisplaying the 3D content and remotely controlling the stereoscopic 3Dglasses.

Of course, as is expected, the very limited availability and expense ofthe above 3D content media playback and display technologies, inparticular, have led to a relative lack of interesting 3D content (dueto the expense in its creation and the very limited commercial interesttherein), which in turn has resulted in a very limited availability of3D content capture and processing tools, thus essentially resulting in a“vicious cycle”.

Nonetheless, in recent years, there has been a revolutionary leap in thesolutions being offered for displaying 3D content media. Specifically, anumber of companies, have developed and offered flat panel displays ofvarying sizes capable of creating a virtual 3D experience for the viewerwithout the need for the viewer to wear electronic or other typesglasses or similar devices. Moreover, these displays do not requireother specialized equipment and can work with specially configured 3Dcontent that may be stored on, and played back from, conventionalreadily available computers. And, while these displays are still quiteexpensive, they are priced within reach of most organizations (andwithin reach of some consumers), with the price certainly poised todecrease exponentially, commensurate with an increase in production (ashas been the case with the HDTV flat panel display market).

Therefore, for the past several years, ever since these neweststand-alone 3D (“SA-3D”) content media display technologies have becomeavailable at relatively reasonable prices, there has been a widespreadconsensus that proliferation of three-dimensional (3D) content media(both in entertainment and in advertising), as well as of the hardwareand software technologies necessary for SA-3D content capture,processing, playback, and display, is inevitable, and that the marketfor 3D-related technologies will experience explosive growth.

Nevertheless, to date there has not been a dramatic push forward thatwould make the above predictions become reality. One of the main reasonsfor this aforementioned lack of the expected proliferation ofcommercially successful SA-3D-related content, software and hardwareofferings, is the fact that although these newest SA-3D content mediadisplay technologies have a number of very significant advantages overall previously known 3D-related offerings, they also suffer from anumber of flaws. Specifically, on the average, the quality and impact ofthe 3D experience delivered by the available SA-3D solutions is lowerthan that of conventional high-end glasses-based stereoscopic 3Dofferings. Moreover the relative position of each viewer to the SA-3Dscreen (in terms of vertical and horizontal viewing angles, distance,etc.) has significant impact on that viewer's overall 3D experience whenviewing the displayed SA-3D content. Moreover, the existing SA-3Dhardware and software solutions for the capture, processing, playbackand display of 3D content media have focused on areas of expertise,offer individual and discrete benefits in various narrow aspects of 3Dand SA-3D technologies with little or no regard for the offerings ofother solution providers, resulting in literally dozens of incompatibleproprietary software and hardware products with nothing to tie themtogether.

It would thus be desirable to provide a system and method directed toone or more modular unifying scalable solutions, preferably implementedin a configurable infrastructure, that greatly improve the quality andimpact of any 3D media content, while decreasing the required levels ofcomputing power, and lowering the complexity of the necessary playbackand display solutions. It would further be desirable to provide a systemand method capable of achieving the above goals by selectivelyperforming 3D content processing and/or settings/parameter configurationat one or more components of the infrastructure from 3D content captureto 3D content media display. It would moreover be desirable to provide asystem and method capable of determining and implementing selective oroptimal storage, transmittal, and application(s) of 3D contentprocessing/settings parameter/profile configuration(s) prior to displayof corresponding 3D content media to one or more viewers thereof.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The system and method of the present invention, address all of thedisadvantages, flaws and drawbacks of all previously known 3D-relatedhardware and software offerings, by providing novel 3D contentmedia-centric solutions that greatly improve the quality and impact ofany 3D media content, while advantageously decreasing the requiredlevels of computing power, and lowering the complexity of the necessary3D media playback and 3D media display solutions, thus maximizing the 3Dexperience produced therefrom for one or more viewers.

The novel system and method accomplish the above goals by providingmodular unifying scalable 3D content-centered solutions, preferablyimplemented in a configurable infrastructure, that greatly improve thequality and impact of any 3D media content, while decreasing therequired levels of computing power, and lowering the complexity of thenecessary playback and display solutions.

In various exemplary embodiments thereof, the inventive system andmethod advantageously enable automatic, semi-automatic oruser-controlled selective performance of 3D content processing and/orsettings/parameter configuration at one or more components of theinfrastructure (from 3D content capture to 3D content media display),and in at least one embodiment thereof, the inventive system and methodare capable of determining and implementing selective or optimalstorage, transmittal, and application(s) of 3D contentprocessing/settings/parameter/profile configuration(s) prior to displayof corresponding 3D content media to one or more viewers thereof.

It should be noted that current 3D media content capture, processing,playback and display solutions take the “lowest common denominator”approach to applying playback/display optimization and related settings(intended to improve the appearance, quality, impact and overall “3-DExperience”) to the 3D content media being displayed to at least oneviewer thereof. This is very problematic because the desirable settingsand parameters, as well as the necessary processing power and otherrequirements, for optimizing and maximizing the quality, impact andoverall 3-D experience level for any displayed 3D media content, varygreatly between different 3D content media files, and even betweendifferent segments/portions within any particular 3D content media fileitself. In particular, these variations largely depend on the specific3D scenes being shown (i.e., on the depicted objects/subjects, theirrelative motion, complexity, backgrounds, lighting, etc.), and on otherexternal factors, such as the original 3D content capture and/orconversion parameter settings, the capture hardware used, the currentdisplay, and even on the viewers' relative position (orientation,elevation, distance, etc.) thereto.

Finally, prior to discussing the various embodiments of the presentinvention in greater detail below, it is important to note that whilemany of the embodiments of the present invention (and the various noveltools, techniques and processes relating thereto), are described anddiscussed as being implemented and/or utilized in the field of 3D visualentertainment (film, television, games, etc., all embodiments of theinventive system and method, can be readily and advantageously utilizedin virtually any scientific, military, medical, forensic, or industrialapplication based on, or involving 3D visualization or display and/ormanipulation of 3D content medial, as a matter of design choice, withoutdeparting from the spirit of the invention.

Referring now to FIG. 1, an exemplary embodiment is shown of aninventive scalable modular infrastructure 10 for selectivelyimplementing, configuring, and managing various components of theinventive system for selectively providing adaptive scalable modularfunctions related to 3D content media capture, generation,quality/processing optimization, enhancement, correction, mastering, andother advantageous processing and/or configuration.

The infrastructure 10 includes optional components 12 and 16 (3D contentcapture system 12, and 3D content processing system 16) for selectivelycapturing and optionally processing 3D content media prior to placing itinto a 3D content media container (e.g., file, stream, etc.). Theinfrastructure 10 also includes a 3D content mediastorage/processing/playback SPP system 18, operable to selectivelystore, process, and/or play back 3D content media from a medialcontainer that may be received from components 12 and/or 16, or that maybe delivered from another 3D content media source (such as mediaconverted from another 3D format, or from non-3D content source).

The SPP system 18 preferably communicates with a 3D content displaysystem 24, operable to display 3D content media (in one or moreconfigurations, and capable of displaying/utilizing at least one of:unprocessed 3D content media 20 a, processed 3D content media 20 b,optimized 3D content setting for use with other 3D media contentreceived from a source outside of the infrastructure 10, etc.) to atleast one viewer (e.g., to viewers, 26 a-26 c).

In at least one embodiment of the present invention, the 3D contentprocessing system 16 may also optionally comprise at least one 3Dcontent processing feature/function that is optimized for utilization inconjunction with the 3D content capture system 12. For example, in oneembodiment of the infrastructure 10, the 3D content capture system 12may actually be a conventional or a modified 3D content capture system,that is provided with additional necessary features (such asscene/visual field depth mapping (or equivalent capabilities) to enabledynamic (and optionally “on the fly”) capture of 2D content, plussufficient depth (and/or related non-image) information that issufficient to enable the systems 12 and 16 to produce desirable 3Dcontent for delivery to the SPP system 18. An exemplary embodiment ofoperation of the infrastructure 10 is discussed in greater detail inconjunction with FIG. 3.

Referring now to FIG. 2, various exemplary embodiments of the possiblecomponents of an inventive system 100, that may be implemented in theinventive infrastructure 10 of FIG. 1, operable to selectively provideadaptive scalable modular functions related to 3D content media capture,generation, quality/processing optimization, enhancement, correction,mastering, and other advantageous processing and/or configuration, thatmay be implemented in the novel infrastructure 10 of FIG. 1. Preferably,one or more of the components (12, 16, 18, and 24), and subcomponents(102 to 114 e) of the inventive system 100, are capable of performingone or more steps of an exemplary novel process 200 of FIG. 3.

Referring now to FIG. 3, an exemplary embodiment is shown as a processflow diagram of an exemplary embodiment of the inventive process, withsteps 202 to 216, that may be performed in whole, or selectively inpart, by at least one component of the inventive system 100 of FIG. 2,or that may be implemented in one or more components of the novelinfrastructure 10 of FIG. 1.

In summary, the inventive system 100 (through selective operation of oneor more components thereof, as may be implemented in infrastructure 10of FIG. 1), in additional exemplary embodiments thereof, preferablyassociates at least one predetermined 3D content improvement (“3DCI”)parameter set (optimization, playback, and/or display settings and/orparameters, selection of one or processing modules and/or stages of usethereof (or example during one or more of: capture, post-processing,playback or display), display tool adjustments, etc.), with 3D mediacontent containers.

In at least one embodiment thereof, the optimal 3DCI parameter setcomprises a plurality of “static to dynamic” display tools adjustments,which may be advantageously recorded and/or otherwise embedded in the 3Dcontent media file, to thereby become a permanent feature thereof duringlater playback and/or processing (e.g., post production, etc.) of the 3Dcontent media. In another embodiment of the present invention, theoptimal 3DCI parameter set integration technique may also be utilized asa playback feature which is interpreted by a proprietary software and/orhardware 3D media player (which, by way of example can be configured asa “set top box” or equivalent, for 2D to 3D content conversion, playbackof “enhanced” 3D content media having an integrated 3DCI parameter set,and for other functions (such as utilization of de-encryption solutionsfor playback of protected 3D content media.

Advantageously, this association and/or linking, occurs on a scalablebasis from the most basic level at which an optimal 3DCI parameter setis associated with one or more corresponding 3D content media containers(that may be in a container directory, a playlist, a queue, or in asimilar storage container), such that the appropriate 3DCI parameter setis activated in conjunction with its corresponding 3D content media fromthe container being played, to a more advanced level at which different3DCI parameter sets are associated with (or otherwise linked or assignedto), the appropriate different portions of each 3D content mediacontainer, such that during playback and/or display thereof, differentsections of the displayed content receive the optimal level of“treatment”.

In one exemplary embodiment of the present invention, theabove-described techniques may be readily implemented in a media player(e.g., software based or otherwise), operable to process and play back a3D media content clip, and which is operable to enable an operatorthereof to: (1) exercise full control over adjustments to 3DCIparameters on a scalable/variable granularity basis (ranging from aportion of a single content frame to a scene formed from a plurality ofsequential frames, and (2) embed various settings and parameters (e.g.,even data points of DCT (discrete cosine transform) settings), andautomatically imbed them in the 3D media content clip for lateroptimized playback.

Advantageously, the novel media player is further operable to enable theoperator to run a 3D media content clip, stop at a particular frame,apply predefined (e.g., DCT) adjustments and record them in the clip,such that the adjustment is automatically carried forward through theclip until the operator stops at a the next frame which requires adifferent adjustment, or the clip ends.

The novel system and method advantageously address and cover both thecreation/determination/configuration of various scalable 3DCI parametersets during 3D content capture, during initial processing, at any othertime up to and including on-the-fly during playback, or any combinationof the above, as a matter of design choice without departing from thespirit of the invention. Similarly, the process ofcreation/determination/configuration of the 3DCI parameter sets can bewholly or partially automated, or can be manually performed as a“creative process” by one or more content professional, preferablyutilizing one or more 3DCI tools and support modules as desired or asnecessary.

For example, tools utilizing novel dynamic and adaptive variable 3Ddepth and layering techniques of the present invention (i.e., DepthBased Image Rendering or “DBIR” techniques), may readily be used forboth automated and content professional-directed 3DCI parameter creation(e.g., the 3DCI may include desired depth adjustment parameters,variable layer densities centered on certain displayed objects or objecttypes, dynamic variable resolution based on relative distance of theclosest object depth layers to the viewer, etc.).

The 3DCI parameter sets may be linked to, or otherwise associated withthe respective 3D content media containers (or portions thereof), andmay thus be stored in dedicated or other form of files, containers orlibraries, separately from the 3D content media containers, or may bestored within the 3D content media containers, (e.g., embedded therein,as discussed above).

The inventive system 100 (through selective operation of one or morecomponents thereof, as may be implemented in infrastructure 10 of FIG.1, for example in accordance with the process 200, or otherwise), invarious additional exemplary embodiments thereof is operable to provideselective, automatic, or user-controlled dynamic/adaptive/scalableutilization of layered depth measurement/mapping (e.g., DBIR) techniquesin 3D content media, coupled with techniques for identifying andspatially (3D) tracking static and moving displayed objects in the depthmapped layered scenes to provide the desired optimal level of at leastone predefined aspect of 3D content experience.

In various exemplary embodiments thereof, the system and method of thepresent invention advantageously comprise the utilization of at leastone of (and preferably both) the following novel 3DCI methodologies(that may be implemented utilizing one or more of various suitable 3Dcontent processing techniques): (1) Dynamic Volumetry, and (2) ViewerPerception Enhancement, each described in greater detail below.

When presenting 3D content using a digital display or a projector, thechallenge is not only to separate the elements of the content into aspatial continuum ranging from foreground to background, but also toreproduce correctly the viewer perspective that would naturally proceedfrom the action on screen. This is true for both content originallycaptured in 3D and for content converted from an original 2D source.

When presented with a visual field containing many objects, the observerwill isolate the objects and focus on a specific one or few in order tobetter interpret the action within the field. The process of separationis based on many criteria/properties such as colour, brightness andrelative motion. Once the objects have been separated, the observer'sprimary focus is chosen. Following that choice, a different set ofperceptual algorithms is used to track the action within the scene. Thecentre of interest is maintained in tight focus and other elements ofthe image which are closer, farther or moving at a different rate aredefocused. Thus, in order to improve the 3D effect of any digitaldisplay, the system used must not only manage the correct definition ofvarying spatial relationship between image elements, it must alsogenerate the presentation in accord with the environmental conditions ofthe display and the perceptual expectations of the viewer.

Essentially, there are two broad categories of activity that take placewithin any 2D-to-3D video transformation pipeline:

-   -   (A) Conversion: Development of a series of data which describe        the calculated XYZ position of picture elements present within        each frame of the video; and    -   (B) Presentation: A mathematical process that shows the        viewpoint of picture elements from different perspectives. (For        example: Two views are required for stereoscopic and 9 or more        for ASD presentations).

Each of the above activities is performed at a different time & place.Conversion is a complex process, typically performed one time only forany given piece of content, whether live or off-line. The conversionprocess is usually performed in a studio or using a separate real-timetechnology module (in the case of live conversion). The Presentationprocesses involve different calculations that are performed at eachviewing time on equipment located at the viewing position. In additionto the methods required to reproduce the basic sub-images inherent tothe 3D presentation technology, the images must be adjusted according toviewer and site-based parameters such as specific output technology,venue physical format, ambient light conditions and viewerposition/preference.

Dynamic Volumetry refers to the process of adjusting the generation ofthe 3D images to compensate for the parameters related to the spatialrelationship between elements within a series of images comprising oneor several 3D scenes. Referring now to FIGS. 4A to 4D, an exemplaryembodiment of the inventive Dynamic Volumetry methodology is shown.FIGS. 4A to 4D show varying volumetric 3Dspaces 300 a-300 d, whichcontain a range of objects of interest 306 a to 306 c arranged fromforeground to background. At different times in the video sequence, thevolume or scale on any or all of the axes will change to allow areasonable discrimination of the objects of interest. Additionally, thesystem performs the sub-image generation with a focus set in a planecontaining the centre of perceived action. FIG. 4A shows a spatialvolume ranging from foreground 302 a to background 304 a and includingan object of interest 306 a

FIG. 4B shows a Perception Focus Plane 308 b At T₀ and a Primary objectof Interest (Perception Focus) 306 b. The positioning of the focus planeis dynamically adjusted to center on the objects or zone with maximumrelation to the action within the image sequence thus permitting thesystem to display the greatest degree of 3D separation.

FIG. 4C shows a side view of 3Dspace and Primary object of Interest 306c. (Perception Focus). Spatial data information can be linear across thespace (foreground to background) or non-linear thus permitting thesystem to display the greatest degree of 3D separation around the areaof maximum interest or action.

FIG. 4D shows Scene Space at T₀ (SS-1) to Scene Space at T_(0+n) (SS-2).The volume of the space is adjusted dynamically to allow the backgroundand foreground to be imaged in such as way as to always include orexclude the zone of maximum interest with the greatest degree of 3Dseparation. Presentation processes involve different calculations thatare performed at each viewing time on equipment located at the viewingposition. In addition to the methods (described above) required toreproduce the basic sub-images inherent to the 3D presentationtechnology, the images must be adjusted according to viewer andsite-based parameters such as specific output technology, venue physicalformat, ambient light conditions and viewer position/preference.

The inventive system and method dynamically modifies a series ofcoefficients/formulae affecting the presentation rendering of a datafile containing and describing the sub-elements of an image sequence(video stream) in such a way as to emulate the natural interest andperception of a view when exposed to a real environment. Themodifications may be based on variables such as the following:

Environment Specific:

-   -   Viewer position    -   Ambient lighting    -   Presentation equipment technology

Content Specific:

-   -   Foreground/background separation    -   Primary activity focus position    -   Overall scene topography    -   Topography of preceding and following scenes

Dynamic adjustments will be at frame speed and may impose specificadjustments for a single scene, a single frame, or an interpolatedsequence of adjustments including linear and non-linear transformsbetween specified points of interest, whether scene-based or not.

Advantageously, in accordance with the present invention, the novelsystem 100 preferably comprises sufficient hardware and/or softwarecomponents and subcomponents to provide and utilize one or more of thefollowing advantageous and novel functionalities/techniques which arecontemplated by the present invention in implementing variousembodiments and aspects of the inventive Dynamic Volumetry methodology:

-   -   1) Automatic/Adaptive Depth layer Acquisition: Utilization of        existing 3D field depth-detection cameras (and related and/or        substantially equivalent hardware) during the 3D content        capture/acquisition stage (or, as may be applicable during the        initial intake stage of 2D content to be converted to 3D), to        acquire a predetermined number of depth layers for the 3D        content to form the desired layered “depth field environment”        for each 3D content frame/scene, etc., which may be the same        depth quantity for the entire container, or which, in accordance        with the present invention, may dynamically, adaptively or        selectively vary for different portions of the content (for        example pursuant to one or more predetermined depth later        variation profiles).    -   2) Dynamic Layer Density Assignment: Assignment of predetermined        amounts of layers to various displayed objects in the 3D content        being captured and/or converted. Optionally, the assignment        process may utilize variable layer density (e.g., depending on        relative depth of different parts of the objects). Alternately,        an object's layer density distribution (or profile) may be        shifted/adjusted dynamically as the object moves within the        depth field.    -   3) Dynamic Focal Layer Determination/Tracking: Determination,        tracking and use of at least one variable dynamically        determined/adaptive “focal” layer (i.e., everything behind the        focal layer needs less detail and less layer density, anything        close needs more) for entire scenes, or for portions thereof.    -   4) Dynamic Multi-Layer Focal Objects/Scenes        Determination/Tracking: Determination, tracking and/or use of        different variable dynamically determined/adaptive “focal        object” plural layers assigned to one or more objects in various        3D content scenes, and that can move to different depths        depending on relative depth positions of the assigned object,        thus enabling variable layer density across objects (essentially        providing, to the inventive system. 100, a control protocol for        simplified manipulation of an object's depth layer        distribution).    -   5) Assignment of Variable Spatial Resolution to Objects: In        conjunction with one or more of the various features above,        utilization of a mixture of different image resolution        magnitudes (pixel density, etc.), and/or optionally of related        image processing (anti-aliasing, etc.), for portions of        objects/scene regions in an optimized manner (for example, by        processing/displaying higher resolutions for those object layers        that are closest to the viewer (or that otherwise would benefit        from additional detail)).    -   6) Geospatial External Calibration: Optionally, maintaining a        selected level of “geospatial accuracy” with external        calibration distance points or with internal software reference        markers, enables visual depth adjustment to precise        geo-spatially accurate images to be accomplished to a degree as        may be desired (or necessary) for one or more 3D content        applications, up to, and inclusive of, extremely dense layering        across each 3D content scene and/or object(s) (for example as        may be required for military, scientific, and/or medical        applications, etc.).    -   7) Application of Dynamic Geospatial Survey Solutions in 3D        Media Content Context: Utilization and/or adaptation of various        advantageous geo-centric survey depth (elevation) mapping        techniques and methodologies to various DBIR techniques utilized        in accordance with the present invention, preferably with        additional modifications applied thereto, to make them dynamic,        adaptive, and highly configurable.    -   8) Additional Novel Tools and Techniques: Selective        configuration, implementation, and use of various additional        features including, but not limited to: dedicated 3D processing        (D3DP) hardware (e.g., “black box”) re-mastering/editing tools,        depth correction techniques, various display/media player        modules and editing tools, streamlining D3DP hardware rendering        conversion processes (e.g., grayscale values to corresponding        layer depth locking, and later image depth        manipulation/correction/optimization via grayscale value        adjustments, etc.), and so forth.

It should also be noted that the various embodiments of the inventivesystem and method, can be advantageously configured, and/or adapted, toutilize and/or combine the very best of currently available (as well asany future) 3D-related solutions in an interoperable manner, that is astransparent as possible to the end user (whether the user is in thefield of 3D content creation, or is part of the 3D content audience).

By way of example, the present invention may be implemented, in whole orin part, in connection with, or utilizing a 2D to 3D video conversionserver (3DVC server), utilizing various additional applications andsoftware-based tools. This technique may employ a variety ofcommercially available software tools designed to provide for somespecific 2D to 3D conversion techniques such as separate interval fieldsequential frame grabbing, and thereafter mixing of the subsequentframes to create a depth map based on horizontal motion (which in itselfis a sub-standard 3D conversion technique). However, when this approach,is integrated with a variety of other compatible 3D content enhancementtechniques, and further assisted/upgraded by the aforementionedinventive system features and tools, it may be configured andimplemented to perform at a substantially higher standard of 3D depthconversion, using one or more suitable DBIR solutions, and thereforebecome an excellent candidate for an inexpensive and easily to use basisfor a Broadcast Quality 3D video standard. It should be noted that theopportunity to integrate a number of commercially available 2D to 3Dvideo depth conversion methodologies with a 3DVC server exists only as aconsequence of the implementation of the various novel depth mappingcorrection and relating techniques of the inventive system 100.

Therefore, the combination of the various commercially available3D-related tools in concert with a 3DVC server, a media player, thevarious novel post-processing and display tools of the presentinvention, unexpectedly and advantageously resulted in the discovery ofa completely unique and new process of image correction, 3D depthmapping, and depth impact optimization, that, when properly used andconfigured in accordance with the present invention are capable ofelevating conventional 2D+Depth (i.e., DBIR) 3D media to Broadcastquality.

The various inventive depth mapping solutions and novel techniques, whenapplied to 3D content media provided by a conventional 3D 3DVC,unexpectedly result in a “remastering” of the 3DVC server, thusconstituting an entirely new commercial application of a conventional 3Dtechnology package “fused” with various novel solutions offered by thepresent invention, and therefore providing a breakthrough opportunity toproduce 3D 2D+Depth stereoscopic 3D content media having maximum depth3D visual impact, but without distracting visual artifacts.

In addition, it should be noted that while a conventional 3DVC servermost is most commonly used to convert 2D content to 2D+Depth 3D contentutilizing one or more DBIR techniques, it is also capable of convertingdual path stereoscopic optical signals to a 2D+Depth format (orequivalent thereof), and is also capable of converting stereoscopicside-by-side and field sequential stereoscopic 3D video, into a 2D+Depthformat (or equivalent thereof). Fortunately, the various techniques andsolutions of the present invention are fully applicable for advantageousutilization in connection with any and all of the aforementionedconversion formats which are supported by the 3DVC server.

Essentially the system and method of the present invention have gone onestep further and readily serve as a basis for producing a 3D softwaresolution (that may be optionally augmented with, or replaced by, ahardware component) that is capable of grabbing stereoscopic pairs froma nine multi-view 2D+Depth conversion, and reformatting them back into aside-by-side, or a dual-path conventional 3D signal, for viewing thereformatted 3D content media using stereoscopic 3D glasses. Accordingly,the inventive techniques close the loop, and allow the use of aconventional 3DVC server to convert 2D content media not only into a2D+Depth format, utilizing one or more DBIR techniques, but to alsoautomatically convert 2D content media into highly desirable andcommercially viable stereoscopic 3D medial content that is necessary forall 3D glasses-based display systems, large and small, thereby enablinga highly attractive and cost effective solution to be offered during theinevitable transition between from 3D glasses-based display systems toASD systems.

When the above-described combined technology package (hereinafterreferred to as a “3DF-3DVC system”) is used with conventional and/ornovel 3D display tool adjustments and settings, (which, in accordancewith the present invention may be readily embedded into a 3D contentmedia file (and optionally recorded/captured “on-the-fly”)), theresulting output not only corrects any remaining 3D video imageissues/flaws, but will at the same time provide the basis fordevelopment and implementation of various guidelines and tools forrapidly effecting a major increase in the impact of the depthperspective visuals in the display of various available and future 3Dcontent media, thus establishing the methodology and infrastructure thatis required for widespread production and proliferation of 3Dstereoscopic video broadcast quality standards.

For example, various inventive 3DF-3DVC system techniques may beemployed in all of 3DVC server applications to effectively upgrade the3D content media quality through “Re-mastering”. When these techniquesare applied to pre-converted 2D+Depth, s3D 3D video clips, which mayhave been produced utilizing one or more DBIR techniques, and designedfor display on conventional commercially available 3D ASD screens,advantageously, the issues of depth error correction, cone double imageremoval and ghosting artifacts may be corrected, and thereforeeliminated.

As a result, in view of all of the above, the use of various embodimentsof the inventive system and method (or of portions thereof), enablescompanies to offer, and consumers and other end-user parties toexperience, 3D content media in a very cost-effective and efficientmanner, thus overcoming the flaws and drawbacks of all prior 3D-relatedofferings that served as barriers to the well-deserved success of the 3Dmedia experience market, and making inexpensive and ready availabilityof the “3D experience” a reality.

Thus, while there have been shown and described and pointed outfundamental novel features of the inventive system and method as appliedto preferred embodiments thereof, it will be understood that variousomissions and substitutions and changes in the form and details of thedevices and methods illustrated, and in their operation, may be made bythose skilled in the art without departing from the spirit of theinvention. For example, it is expressly intended that all combinationsof those elements and/or method steps which perform substantially thesame function in substantially the same way to achieve the same resultsare within the scope of the invention. It is the intention, therefore,to be limited only as indicated by the scope of the claims appendedhereto.
